Richness and abundance of epigeal macrofauna in four tropical systems of Chiapas, Mexico
We sampled four vegetation systems with different degree of disturbance (i. e. tropical forest, mature and young secondary forest, and a cornfield) in northern Chiapas, Mexico.

| description | We sampled four vegetation systems with different degree of disturbance (i. e. tropical forest, mature and young secondary forest, and a cornfield) in northern Chiapas, Mexico. The objective of this study was to determine the differences in the composition and structure of macroinvertebrate communities in litter. We estimated abundance (N), species richness (S), Shannon’s diversity (H´), Pielou’s evenness (J), and Morisita-Horn’s similarity index. Twenty samples were randomly placed in each system by using 1-m2 quadrats. Leaf litter and organic matter (humus) were collected from the quadrat to a depth of 5.0 cm, with the purpose of collecting only the epigeous macroinvertebrates. We collected 1,259 specimens from three phyla, nine classes, 26 orders, 61 families, 17 genera, and 100 morph types. The highest N and S were observed in the tropical forest, however, the highest diversity (H´) occurred in the young secondary forests. The cornfield showed the highest evenness. There was a positive relation between the systems’ conservation level and macroinvertebrate abundance, but not with species richness. |

There was a positive relation between the systems’ conservation level and macroinvertebrate abundance, but not with species richness. Se realizó un muestreo en cuatro sistemas vegetales con diferente grado de perturbación, (i.e. selva tropical, vegetación secundaria madura, vegetación secundaria joven y un cultivo agrícola) al norte de Chiapas, México. El objetivo de este estudio fue determinar las diferencias en la composición y estructura de las comunidades de macroinvertebrados presentes en la hojarasca. Para ello, se estimaron datos de abundancia (N), riqueza especifica (S), diversidad de Shannon (H´), equidad de Pielou (J) y el índice de similitud de Morisita-Horn. En cada sistema se tomaron 20 muestras colocadas al azar por medio de cuadrantes de 1 m2. Se recolectó la hojarasca y materia orgánica (humus) del cuadrante hasta una profundidad de 5.0 cm, con la finalidad de colectar únicamente a los macroinvertebrados epigeos. En total se obtuvieron 1,259 especímenes, clasificados en tres phyla, nueve clases, 26 órdenes, 61 familias, 17 géneros y 100 morfotipos. La mayor N y S se encontraron en la selva, sin embargo, la mayor diversidad (H´) ocurrió en la vegetación secundaria en etapa inicial de sucesión. El cultivo agrícola se mostró como el sistema con mayor equidad. Se observó una relación positiva entre el grado de conservación de los sistemas con la abundancia de los macroinvertebrados, pero no siempre con la riqueza de especies.
